Specification of Letters Patent.

Patented April 28, 1908.

Application filed August 30, 1907. Serial No. 390,713.

To all whom it may concern:

Be it known that I, HARRY W. DYER, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Revolving Doors, of which the following is a full, clear, and exact description.

My invention relates to revolving doors of the type in which the door comprises a plurality of wings extending radially or substantially so, and in which one or more of the wings are hinged with respect to each other, so that they may be folded, thus affording a free passageway whenever desired, and in which the door when folded may be moved to one side of the passage if desired, so as to leave the same entirely free for substantially its entire width.

My invention has for its object the provision of improved means for bracing the movable wings and for locking the same when open and when in folded position; also improved means for locking the door in the position which it occupies when acting as a revolving door; also improved means for rota tably supporting the door and for carrying the door from its normal or rotary position to one side so as to leave the passageway free; also the provision of means for moving the said door from its normal position to one in which the passa eway is substantially unobstructed; and iinally the provision of improved details of construction, as hereinafter set forth and claimed.

Reference is hereby made to the accompanying drawings of which,

Figure 1 is a section on line 1-1 of Fig. 2; Fig. 2 is a front elevation partly in section showing a door constructed in accordance with my invention, and showing in section the adjacent parts of the structure of the buildin to which the door is applied; Fig. 3 is an en arged section on the line 33 of Fig. 1 Fig. 4 is an enlarged section on line 44 of Fig. 2; Fig. 5 is a detail front view of the lock for holding the sections of the central rod of the door in raised or lowered position; Fig. 6 is a section on line 66 of Fig. 5 Fig. 7 1s a detail section showing one of the edges of the door with the weather strip applied; Fig. 8 is a detail sectional view of the lower end of the central rod and its supporting shoe; Fig. 9 is a detail section of the up er or lower edge of one of the wings of the cor showing the weather strip; Fig. 10 is a plan view of the turn table from which the door is suspended; Figs. 11 and 12 are detail views showing the mechanism for locking one of the hinged wings of the door in its open and closed positions, and Fig. 13 is an elevation showing the mechanism for operating the turn table for moving the door from its central or rotary position to one side of the passageway.

In all the views corresponding parts are designated by the same reference characters.

The door shown comprises a support or body 1, formed with a pair of oppositely disposed wings H, and rotatably supported by a central axis in the form of a sectional tube V. Within the body 1 of the door is a block H preferably of metal, formed in two parts, as shown in Fig. 8. These blocks I-I carry the entire weight of the door, and apply the same to the block WV, which forms a part of the roller bearing E carried by the turn table, the weight being transmitted through the sectional tube V, the upper member V of which is threaded within the bearing block W, and the upper block H The intermediate member V is threaded within and connects the upper and lower blocks H and the lower member V is threaded within the lower block H It will be thus seen that the entire weight of the door is carried by the blocks H and tubing V, by which the weight is applied to the ball bearing. The body of the door therefore rotates freely about its axis which is held in its normal position by a sectional rod U. The sections of the said rod are vertically movable, and means are provided for raising and lowering the said sections when desired and for locking the same in either position. In the position shown'in Fig. 3, the upper section is in its elevated position, the upper end occupying a socket in the block T, and the lower section is in its depressed position, so that the end of the shoe X engages a socket in the block Y, which is sunk in the floor. The shoe X is a tube within which the lower end of the rod U is threaded. The bottom of the shoe is closed and formed with a stud for engaging the socket of the block Y. The door therefore cannot be moved from its normal or rotary position, unless the sections of the rod U be moved longitudinally so as to withdraw the ends of the same from the blocks T- and Y respectively. The means for accomplishing this result is illustrated in Figs. 3, 4 5 and 6. A recess 2 is formed within the body 1 and a similar, but narrower recess 3, is formed within the block H These recesses as will be seen are closed when the hinged wing is open or in radial position, so that there is no access thereto at such time, but the move ment of the wing upon its hinge, exposes the said slot so that it then becomes possible to raise and lower the upper and lower sections of the rod U. WVithin each of said sectionsis set a piece 4, which extends through the slots 2 and 3. The outer end of said. piece 4 is forked, and within the same a lever D is hinged by a knuckle oint, so that when in its vertical position it occupies the slot 2 and lies entirely within the body 1 of the door. In the position shown in full lines in Fig. 6, the lower end of the member D rests upon the bottom of the slot 2, and thereby suports the rod U. When the lever D is rought out into a horizontal position, it serves as a handle for lifting the section U, and when in its elevated position, (shown in dotted lines) it holds the rod U in an elevated position by reason of the lower end of the member D resting upon shoulders 5 5, formed in the side walls of the slot 2. The construction of the device C for raising and lowering the upper section of the rod U is identical with the structure which has been described for the operation of the lower sec tion of the said rod.

The hinged wings H which are adapted to be folded with respect to the body of the door are carried by the hinges B and are normally held in radial position by means of the hinged braces B. They are locked in this position by the following means: The fixed wing H carries a piece D, having an outwardly projecting arm to the end of which is pivoted a hollow or tubular member C, and within the same is telescoped a rod C one end of which is pivoted to a piece F secured to the hinged wing H. l/Vhen'the hinged wing is in the position shown in full lines in Fig. 4, the rod C is almost entirely within the tube 0, and in this position the detent 6 of a locking-latch K (Figs. 11 and 12) which is hinged upon the tube C, engages a recess 7, formed in the rod C thus preventing the rod from moving longitudinally with respect to the tube C. Upon the movement of the latch K as indicated in dotted lines in Fig. 11, the detent 6 is withdrawn from the recess 7, and the wing H can be moved upon its hinge into the position indicated in dotted lines in Fig. 4. This movement causes the rod 0 to move longitudinally with .respect to the tube 0, and when the position shown in dotted lines is reached, a second recess similar to the recess 7, and which is formed in the rod C comes opposite the detent 6 of the latch K which may be moved so as to engage said recess, thereby locking the hinged wing H firmly in its folded position. The door is then in suitable form for being moved bodily or translated to one side so as to leave a free passageway. This is accomplished after withdrawing the ends of the sectional rod U from their sockets, by a rotation of the turn table before referred to. This turn table is preferably seated. above the ceiling over the door, and comprises a base 0, sup porting a circular track P, shown as a channel, a spider R, upon the ends of whose radial arms are mounted rollers Q which rest upon the track P, an d a disk N, which is firmly secured to the spider R by the straps S, so as to turn with said spider. The tube V passes through an opening in said disk N and the latter being concentric with the track P, at all times closes the circular o ening formed in the ceiling above the door or the passage of said tube V. One of the radial arms of the spider R is enlarged to form the cup of the roller bearing E which supports the tube V, which carries the revolving door. It is obvious that if desired the turn table may be caused to rotate by merely pushin the door from the position indicated in fufi lines in Fig. 1 to that indicated in dotted lines, whereby the door describes a circular path, and this is usually the way in which the device will be operated, but in some in stances, as, for example, where very heavy metallic doors are used, -it will be desirable to provide mechanism for causing a rotation of the turn table, and thereby producing the desired movement of the door. Such means may be of any type or form whatever, either electrical, pneumatic, mechanical, etc., but I have shown for this purpose a mechanical movement comprising a circular rack 8, applied to the spider R, with which engages a pinion 9, carried on the end of a horizontal shaft 10, the other end of said shaft being provided with a sprocket 11, over which passes a chain 12, said chain also passing over a sprocket .13, carried by horizontal shaft 14, which may be operated by a crank 15. When the door is in its folded position at one side of the passageway, it may be locked by means of vertical bolts L, applied 'to the top and bottom edges thereof (see Fig.

2), said bolts engaging suitably located sockets in the floor and ceiling, and being controlled by locks L. The same bolts are also useful for holding the door while in its normal or rotary position, so that it will completely close the passageway, and will prevent any unauthorized person from entering the building, as, for example, when it is desired to close the building at night. All that is necessary is to provide suitable sockets in the floor in the proper positions to cause the door to com letely close the passageway, as when turnecf through an angle of 90 degrees from the position shown in full lines Fig. 1.

The use of a turn table for imparting a movement of translation to the folded door is advantageous in that it permits the ceiling to be practically without any opening, since the disk N fits closely, and there is only suflicient space around its periphery to permit it E to rotate freely. Another advantage is that the translating movementmay be effected by pushing against the edge of the folded door in the direction of its width, thereby concentrating ones weight upon the door, so that one man can move a heavy door, which he might not be able to do by pushing against the face of the door, since in this case he could not concentrate his weight at one point, because the door would tend to rotate and pressure would have to be applied at points on opposite sides of its center. A further advantage resides in the fact that the frictional resistance of the translating device against movement may be reduced to a minimum.

- 1. The combination of a turntable support, a turntable carried thereby and having at least three points of support spaced around its circumference, a roller at each point of support, a door comprising radial wings, and means for rotatably supporting said door upon said turntable at a point eccentric thereto and at a distance from the center thereof which does not exceed the distance of one of the supporting rollers from said center.
